21 Control Selectors
Publication 2711E-6.15 – November 1998
The Control List Selector with Enter Key recognizes when the
Selector Control value is changed externally. For example, if the tag
assigned to the Selector Control is also assigned to another object,
and this object sends a new value to the tag, the Control List
Selector’s highlight bar moves to the list state that has this value
assigned. If the state value doesn’t match the tag value, the highlight
bar will be removed. An error state also occurs if the Selector
Control is not assigned. In this case also, no highlight bar appears.
If the Selector Control cannot accommodate a state value, an error
message is displayed, and the PLC value is not changed. The
operator must clear the fault before continuing.
Important: For Remote I/O applications, and ControlNet Scheduled
tags, the PanelView terminal can retain the current
value for the Control List Selector with Enter Key, even
after the terminal is turned off. Depending on how the
Application Startup operation is defined, the retained
value (last state) or initial value (default) is sent to the
PLC when power is reapplied.
For DH+ applications, ControlNet Unscheduled tags,
and Modbus applications, the current value cannot be
retained. Depending on how the Application Startup
operation is defined, the initial value or nothing
(default) is sent to the PLC when power is applied.
For details on configuring Application Startup
operation, see “Application Startup” in Chapter 5 of the
PanelView 1000e, 1200e, and 1400e Operator
Terminals User Manual.
Configuring a Control List Selector with Enter Key
Configure the Control List Selector with Enter Key according to this
table:
Field Meaning
Name Assign a name, up to 15 characters, to document the object for
printed reports. This increases the application’s size by 1 byte
per character.
Control List Type Specify Control List Selector with Enter Key.
Initial State Specify the state that the cursor defaults to when the
application is run for the first time. Choose any of the states in
the list.
Instead of assigning a state, you can enter a blank value in the
Initial State field. This means that the object will always use the
Selector Control’s initial value to set the initial state.
